Highway 29 was closed for four hours as investigators examined evidence sprawled across the two-lane road, forcing motorists to take a detour through Cobb Mountain on Highway 175.

The bicyclist was a resident of Lower Lake. Lake County sheriff's officials were still notifying his family late Tuesday and his name wasn't released.

Hubbard's 1999 Chevrolet Suburban apparently clipped the bicyclist on the highway north of Clayton Creek Road, the CHP said. The bicyclist spun around and ended up in the middle of the road.

Hubbard "did not stop at all," Domby said.

But two other people in northbound vehicles saw the man and his bike in the road and pulled over to help, Domby said.

The bicyclist was stirring on the roadway and may have been trying to get up when a 2008 Toyota Prius driving north on Highway 29 came upon the man and ran over him and his 24-speed Fuji bike, Domby said.

The Toyota driver, John Weeks, 62, of Hidden Valley Lake, stopped and stayed at the accident scene.

The bike rider was pronounced dead at the scene.

The CHP issued a public alert for a hit-and-run driver in a black SUV in connection with the dual accidents.

At about 9:40 a.m., CHP officers were contacted about a distraught woman who was at the Clearlake Police Department.

She said she thought she'd hit a deer earlier in the morning on Highway 29 with her burgundy Chevrolet. But she'd later heard a person had been hit and killed in the same area, according to a CHP dispatch log.
